Abstract

Embodiments of the present disclosure provide techniques for improved fluxgate current sensor. A fluxgate signal (120) corresponding to a primary current may be received. The fluxgate signal may include at least two plateau periods (210A, 210B). Each plateau period may define a plurality of candidate calculation windows (330A). An operation condition classification may be generated based on a signal characteristics set by applying the signal characteristics set to a classification model. The operation condition may be one of an AC operation condition or DC operation condition. A calculation window may be selected based on the operation condition classification. The plurality of calculation windows may include a first calculation window and a second calculation window. A predicted current value may be generated for the primary current by applying sampled current values within the selected calculation window for each of the at least two plateau periods to a prediction model.
